I'm going through a tutorial, which has me save a program and then attempt to run it using the "wish" command. I attempted this from the bash terminal window, but get an error because bash doesn't recognize "wish." What do I need to install for this to run? (I've loaded all the suggested TCL libraries).

EDIT: I got it working; I got lazy when entering the path to export, using the tab key, which omitted the version # of the TCLTK directory. Hmm...
